About TaxGPT
TaxGPT is what it sounds like: a generative-AI copilot built specifically for tax. Ask a complex federal, state, or Canadian tax question and it returns an answer with citations to the underlying authority, drafts tax memos, and auto-writes replies to client emails and IRS or state notices.
Founded in 2023 by Kashif Ali and Isabella Maceda-Ali and backed by Y Combinator with about $5.2M raised, TaxGPT reports 10,000+ CPAs, tax lawyers, and enrolled agents using the professional product, plus consumer and freelancer tiers with a free monthly question allowance.
A conversational AI fine-tuned on CPA- and tax-attorney-vetted sources answers tax questions with citations, drafts memos and IRS notice responses, and reports 650,000+ questions answered.
Highlights
- Used by 10,000+ tax professionals serving roughly 250,000 clients
- Backed by Y Combinator; raised ~$5.2M including a $4.6M round in February 2025
- Offers consumer and freelancer plans alongside the professional product, including a free tier
